When it is switched on, the battery icon is always visible on the display and indicates the amount
of energy still available. Period of operation can be up to 1000 hours, depending on the power
supply, network configuration and the type of operation programmed.
Should the energy source be virtually used up, the empty battery icon starts to blink and a regu-
lar reminder tone sounds. There is still an operating time of at least 24 hours available. By press-
ing the confirmation key, the battery alarm is switched off, the empty battery icon, however, con-
tinues to blink.
